Subject: [PATCH 1/2] mfd: stm32-timers: fix pwm-stm32 linker issue with COMPILE_TEST
Date: Fri, 18 May 2018 17:24:03 +0200 [thread overview]
Message-ID: <1526657044-14879-2-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1526657044-14879-1-git-send-email-fabrice.gasnier@st.com>
This is seen when COMPILE_TEST=y and MFD_STM32_TIMERS=n.
drivers/pwm/pwm-stm32.o: In function 'stm32_pwm_raw_capture':
pwm-stm32.c:... undefined reference to 'stm32_timers_dma_burst_read'
Fixes: 0c6609805b63 ("mfd: stm32-timers: Add support for DMAs")
